This guide for developers delivers practical advice and code samples to help readers master Web service constructs and provide interoperability between heterogeneous servers and clients. Focus is on the auto-generated proxy classes used by Visual Studio 2003 and 2005 for managing communication with Exchange Web Services. In addition to discussing the raw XML structure of the SOAP messages passed between a client application and Exchange Web Services, the book also includes a number of examples of how to program using the auto-generated proxy class. Part I covers basics of Exchange Web Services. Part II covers all of the item and folder types that can exist in a Mailbox, and Part III discusses the restriction architecture in Exchange Web Services. Part IV covers Mailbox alerts, and Part V covers advanced topics. The book is for developers who will be writing applications that use Exchange Web Services to talk to Exchange Server 2007. Readers should be familiar with the Microsoft .NET 2.0 framework and the C# programming language. Previous exposure to programming against Exchange using any other API is not required.
